Handyman Question....

My AC went out last evening (fortunately, the house fans were cool enough to sleep) and I resetted all the circuit breakers.....still nothing. Being hurricane season, there's a lot of lighening/thunder storms on a daily basis and last evening we had a minor one.
Although the AC unit and thermostat seem to be working fine, the fan outside wasn't turning. So, this AM I turned the fan outside with a stick and it started.....YAY!! (but, I'm thinking the capacitors are dead and need replacing). 
 
How difficult is it (for a non-handyman as myself) to replace the capacitor on my Trane HVAC? (too dangerous???.....lol I don't want to get zapped, but don't mind learning how to do it). Of note, I'm also going to call a licensed AC guy to do some maintennance before summer arrives (should I have him replace the capacitor?). Sorry, I'm a complete noob in this....

Hey Mesh - Isn't it more likely it was just a twig or whatever causing the trip that you cleared out of the fan by rotating it? If it is indeed the capacitors, they need to be properly discharged before replacing them, which could pose quite a hazard if you are unfamiliar with how to do this.
On edit - someone with a lot more skill than me might be able to fill in the holes.

The twig/leaves are a very likely possibility Brando (unrelated to the fan, there was a dead squirrel that was stuck on top of the grill just hanging, but not touching the fan blades)......I'll see if the fan wil restart once the desired temp. is reached. The whole unit is only 5 years old (I bought the house less than a year ago, but never had the AC serviced).
From the little I've read, it seems that capacitors are universal parts and the main number to exactly match is the micro-farad......(even if I don't replace it myself, I thought it might be good to have an extra one for the future.....then it's only the labor that I have to pay). 
I'm more inclined to have someone who knows what they're doing than take a stab at it, but just wanted to see how complicated the process might be.........not at the cost of getting electricuted though.

My gut feel is with Brando... much more likely that you dislodged a physical obstruction.
 
However, I am assuming that it is a straight-up AC inductive motor (no capacitors except for the control board), so it is possible that it is a 4-pole motor and one of the windings is shorted (is unlikely, but possible due to water exposure). This is easy to check though, as simply shutting it off and turning it back on several times would let you know (sometimes it would energize and hum, but not move). I have only seen this once in my lifetime (on a garbage disposal where water had damaged the windings), but I actually "kick started" it for a couple months before I got sick of it.
 
To be honest, the safest (and best learning for you) method is to have a qualified tech look at it and be there and talk to him as he assesses it. People truly love to talk about what they do, and you can learn a lot from something so simple (just keep asking things ).

If you're dealing with electricity and you don't know exactly what you're doing, it's helpful to keep in mind how many volts you don't know what you're doing it with.

 In order, then, to discover the limit of deepest tones, it is necessary not only to produce very violent agitations in the air but to give these the form of simple pendular vibrations. - Hermann von Helmholtz, predicting the role of the electric bassist in 1877.

The fan is important, but if the compressor doesn't start, all you are doing is moving air.
It is basically a high torque pump, and needs a boost to get it turning. This is what the capacitor is for.
Think of the capacitor as a "burst battery". It provides a significant, short duration burst of power to start the compressor motor. It will gladly share that power with you, if you're not careful. On the other hand, a dead capacitor is fairly inert.
The capacitor is the cheapest and most likely cause of your problem, but it would probably be worthwhile to have you HVAC guy handle it.
 
Hmm. Looking at the time, you probably have it fixed by now. Hope everybody is comfy.

Re: Handyman Question.... 2015/04/22 07:54:40 (permalink)
There are several things that could be the problem.  The motor not starting could be any one of several things....  bad capacitor, shorted or burned out coil, burned up relay, burned wire connection.  
 
I have replaced a few motors and caps in my time but have also run into compressors with bad bearings that seized up when I put a booster cap on it to get it going. It made one heck of a racket for the 4 seconds it did run... then BANG!!!  Silence...... OK... not good..... time to call my local HVAC guy.
 
While the HVAC crew isn't cheap, they do, for the most part, know how to troubleshoot and find the actual problem and get it repaired quickly, vs you trying part after part and since most stores will not take returns on electrical parts, you're out that money too.
 
My last case, with the compressor not starting.....I tried the booster cap.... $29, and that didn't solve the issue...... we ended up having to replace the HVAC gas pack due to it's age and the cost of replacing the compressor and still  having a 20 year old gas pack setting there. I used that opportunity to have everything... including the ductwork under the house replaced with all new. They were in bad shape.
 
Most of the time, when my HVAC system fails, it's either raining, snowing, generally at about 10pm when it's dark..... it rarely happens in the morning of a nice spring day.......  I had a blower fan go bad at 10pm on the coldest night of the year and there was an ice storm going on.  My daughters had to use extra blankets in their upstairs bedrooms that night..... next day, I got a new motor and had the split unit blower running by noon.
 
It's always something..... oh the joys of home ownership.

Outside compressor fan not working usually means a bad relay in the outside unit=easy to fix. Everything working but not moving air inside can mean a frozen or clogged evaporator coil or the air handler fan not working. A clogged filter could also restrict air flow .

Thanks all for the great info!!
 
On Friday evening, the AC tech came over and confirmed it was the capacitor that went bad (which is apparently a common thing here in FL from the regular lightning/storms). He replaced that and I also had him service the unit. Everything was done in under 30 minutes (in the rain) and he charged me $182.....which seemed like a reasonable price (compared to some of the other estimates).
 
The good thing I like about this company is that the owner asked me to check around (reviews/word of mouth etc....) before deciding to hire him as he's been in the area for 30 years doing the same type of work......I did confirm with some locals and all his reviews were very good......I'd definitely hire him again as (like Herb stated) he knew his job very well and was a very simple/easy to talk to guy.
 
I would've definitely called a handywoman to do the job, but there apparently had been a BOGO shoe sale at the mall.

My AC went out last evening (fortunately, the house fans were cool enough to sleep) and I resetted all the circuit breakers.....still nothing. Being hurricane season, 



HUH, we dont start hurricane season until June down here then August and September are the bad months
 
Hope you get it fixed economically and quickly

Yeah, possibly more like a pre-seasonal monsoon hurricane weather (did have some 50+ mph winds last week with hail storms as well).
Thanks MM, I got the AC fixed (see post #20).
